I blindly went along with my doctor prescribing the Fentanyl
patch along with other meds for BT pain. I realized the Fentanyl
had a lot of negative things for me (like increase in sugar intake, nodding off when I stopped doing anything, no short term memory.) Do a search on Fentanyl here and see what people have gone through with it.
Personally I think it should only be used for end of life pain. If you have reason to think you won't ever come off it, then it would be okay.
